Application filed February 9, 1916. Serial No. 77,209. f v

wherein the leaves thereof which are ar! ranged in series and superimposed upon each other will be firmly held to ether and the spring as a whole will be firm y clamped at the points of connection thereof with the vehicle axle or frame without weakenin the spring at this point or points resultant rom perforating the same for accommodating a center bolt which as usual-is passed there-l through for securing the spring in place.

Another object of the invention is the provision of a spring of this character wherein the same is materially reinforced at the point where it is secured to an axle and also the leaves are prevented from slipping relative to each other and the spring as a whole is prevented from displacement upon the axle or the side beam ofthe truck frame of the vehicle.

A further object of the invention is the provision of a spring of this character which is simple in construction, reliable and efficient in operation, possessing maximum resiliency, strength and durability and also which is inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth. j'

The invention accordingly consists in the features of construction, combination of elements and varrangement of parts which will be exemplified in the construction here-A inafter described, and the scope of the ap-l plication of which will be indicated in the claims appended hereto.

In the accompanying drawings: Figure 1' is a perspective view of a spring embodying the features of the invention; Fig. 2 is a fragmentary vertical longitudinal sectional view thereof; Fig. 3 is a fragmentary plan view; Fig. 4 is a horizontal longitudinal sectional view through the housing or shell embracing the spring; Fig. 5 is a sectional view on the line 5`5 of Fig. 1; Fig. 6 is a fragmentary perspective .View of the leaves of the springs arranged 'in relative position...

Similar-'reference characters indicate corresponding parts throughout thel several views of the drawings. 3 w l Referring to the drawings in detail, l'5

and 6 designate the upper and lower bowedn leaves of an elliptical shaped spring, the leaves being arranged in series'and super imposed upon each other inthe make-up of thel spring. The upper and lowerseriesfofr leaves are corrugated, at` 7 .oni-'opposite ledges thereof` medially of the same for a purpose presently` described. lleoeivingf each series of upper and lower leaves 5 and G of the spring is a housing or shell 8 preferably made from metal and open at its bottom, the side walls of thesaid shell 8 Y being formed with corrugations `9 corre-v sponding to the corrugations 7 on the leaves of the spring. Formed at opposite ends of the housing or shell 8 are easements or hollow beads 10, in which -are received U-shaped clips 11 which are formed with threaded ends 12 for accommodating nuts 13 which are adapted to secure upon the clips 11 cross plates 14, vthe same being suitably perforated tojaccommodate the limbs of the clips 11, and in this manner the housing o r shell 8 is firmly and securely clamped about the series of either of the upper and lower leaves 5 and 6 of the spring. vAll the leaves of each series are corrugated eorre.

spondingly to each other so that when the same are embraced by the housing or shell 8 the said leaves will be prevented from disl placement relative to each other, thus avoiding the possibility of the working loose of any one leaf in the series.

It is off. course understood that one or more axle clips or clamps can be fastened about a' housing or shell and at the points of vengagement of the same therewith the corrugations 9 are widened to accommodate the said clamps or clips and likewise the corrugations 7 on opposite edges of the leaves of the spring are correspondingly widened.

lVhen the housing embraces the'lea'ves of. the spring the same are firmly held together to prevent slipping of any one or more leaves relative to each other and also the slipping of the spring upon the axle or side4 beam of the truck frame of the vehicle. By reason of this particular form of clamp or housing the spring is materially reinforced and the necessity of. perforating the leaves for the receiving of a bolt to hold the separate spring leaves together is eliminated because in so doing the spring is materially vweakened with resultant breaking at vthis .claim l. A vehicle spring comprising a plui rality of superimposed leaves having opposite corrugated edges for a distance thereof, and a housing embracing the superimposed leaves and having corrugations in correspondence to the corrugations on said leaves.

2. A vehicle springcomprising a plurality of` superimposed leaves having opposite corrugated edges for a dista-nce thereof,

a housing embracing the superimposed leaves and having corrugations in correspondence to the corrugations on said leaves, and means -for rmly clamping the housing about the leaves of the spring.

A vehicle spring' comprising a plurality of superimposed leaves having opposite corrugated edges for a distance thereof, a housing embracing the superimposed leaves and having corrugations 'in correl spondence to the corrugations on said leaves, means 4for firmly clamping the housing about the leaves of the spring, and beads formed at the ends of the housing for re. ceivingthe said means.

In testimony whereof I affix my signature in presence of two Witnesses.
